    • A transceiver preferably embedded within a wearable security watch, PDA, or other device which achieves a variety of wireless ultrasonic and/or radio-frequency based functions, including digital identification and proximity and sensation monitoring of assets, individuals, pets, and the like. The portable or wearable device realizes these functions by periodically polling and receiving information tags within the transmitting distance of the device. The invention can help reduce the likelihood of the theft, loss, or misplacement by detecting that a tag associated with or attached to an entity has left an individual's proximity and sounding an alarm. The device can also assist individuals with sensory impairments, including persons who are deaf, diabetic, and the like, by detecting a tagged entity as it enters the space around an individual, or by detecting environmental stimuli, such as excessive heat in an individual's proximity or vital sign changes, and sounding an alarm.
    • 优选地嵌入在可佩戴的安全手表,PDA或其他设备内的收发器,其实现了各种无线超声波和/或基于射频的功能,包括资产,个人,宠物等的数字识别和邻近感觉监测。 便携式或可穿戴设备通过在设备的传输距离内周期性地轮询和接收信息标签来实现这些功能。 本发明可以通过检测与实体相关联或连接到实体的标签已经离开个人的邻近并发出警报来帮助减少盗窃,丢失或错位的可能性。 该装置还可以通过在标记的实体进入个体周围的空间中检测标签的实体,或者通过检测环境刺激,例如个体接近度中的过热来帮助患有感觉障碍的个体,包括聋人,糖尿病患者等 或生命体征改变,并发出警报。
